[PATCH] gitk: do not show local changes when we there is no work tree

From: David Aguilar <davvid@gmail.com>
Date: Mar 10, 2008, 10:54 UTC
Message-ID: <309f000ad75b1842c11a04b16940dda8f1cd84af.1205145018.git.davvid@gmail.com>
In-Reply-To: <18386.29988.380116.517508@cargo.ozlabs.ibm.com>

Launching gitk on a bare repository or a .git directory would previously show the work tree as having removed all files. We now inhibit showing local changes when gitk is not launched from within a work tree.
